TO ALL WHOM- IT MAY CONOERN:

Be it known that I, HENRI- JUGE, ot' New York city, county and State of New York, have invented a new and improved Eylet-Inserting Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being hadto the accompanying drawings, making a part of this specification, in which- Figure 1 is a perspective view ofthe improved eyelet-inserting machine complete.

'Figure 2 is a vertical transverse section through the working parts of the machine in position for receiving an eyelet. V

Figure 3 is a vertical section taken in a plane at right angle to the plane of the section of iig. 2, showing the parts in the act of clinching an eyelet. y

Figuresl and 5 are enlarged sectional views showing the perforatingand elinching devices in two positions.

Similar letters of reference indicate corresponding parts in the several iigures. i

This invention relates to certain novel 'improvements on devices which are designed for the insertion and clinehing of eyelets in cloth, leather, paper, and other substances. The invention consists mainly in combining, with the devices which turn over and clinch the edges of eyelets, a tubular cutter or punclnwhich will cut holes through leather, cloth, and other like substances, previously to the insertion of the eyelets, and which will, at the same time, serve as a central guide for receiving the eyelets and holding them while being clinched, as will be hereinafter described. Another part of my invention consists in the employment, in conjunction with acuttingand elinching device, of an adjustable stud for gauging the spaces between the eyelets while inserting them in the substance, so that the eyelets can be inserted at regular distances apart withoutpreviously spacing oil' the substance which is to receive them, as will be hereinafter described.

To enable others skilled in the art to understand myinvention, will describe its construction and operation.

The frame which supports the perforating and elinching devices, and the parts which. are used for operating these devices, consists of a C-shaped plate, A, having projecting jaws, a a, on its back,'through one of which jaws an adjusting screw, a', is tapped, by which the frame can be clamped iirmly to the edge of a table or other fixed object. The upper end of the frame A has a hollow cylindrical enlargement, formed on it, the axis of which coincides with the axisof a longer tubular enlargement, c,which is formed on the lower end of the frame A, as shown in figs. 1, 2, and 3. The lower end of the tubular enlargement c terminates in two ears, cZ between which the ca1n-lever B is pivoted by a pin, c.y Through the tubular holder o a hollow stenn, of a tapering collar, el, passes and receives upon its upper end a nut, e2, which-confines the collar` el `rmly in place upon the lower end of the holder b. The hole which is made through the holder 6 may besomewhat large'liithanthe tube or stem e of the collar el, so as to admit of this collar being adjusted and set exactly in the fc"e`i1`t`rc of the device which is arranged below it for receiving the eyelets. Into the lower end of the collar elthe` die, which spreads and elinehes the upper ends of the eyelets, is screwed. This device has an annularldepression'formed"in its lowerend, and from its centre projects a tube,f, the lower end of which is sharpened for cutting holes through cloth, leather, or paper. This tubular cutter or pnnchj` may be formed on the die f', or it may be made separate and screwed therein. It may be made slightly tapering so as to commence spreading the upper end of the eyelet as soon as received thereon, as shown in iig. 5. Beneath the punch and die, above described, is a die or elinching head, y, which has a central hole through it through which a cylindrical stem or eyelet-holder, 7i, passes freely. This tubular elinching head g is screwed into the upper end of a tube, z', which moves up and down inthe holder c, and is guided at its upper end by a ilanged collar, j, which is secured to the upper-end of portion c, as shown in figs. 2 and 3. The lower end of this tube is slotted and roundcd, `as`sho\rvn kiri igfQ, and sustained upon the slotted cam-head B of lever B. This tube t' is forced down upon "the"c'ainls.` url'ace of head B by a coiled spring, 7c, which will yield and allow the head g to be moved'up to thcmpositionshown in figLVS,

by depressing lthe lever B, as indicated in dotted lines, iig. 2. When this lever B is released the spring will move the parts z' and B to the position shown in iig. 2. Within the tube z' is aired, it', carrying on its upper-end the stem 7L and a spring, Z, and receiving in a vertical slot, which is formed in it near its lower end, a guide-pin, m, which prevents it from turning in the tube The lower end of the rod 7L is bevelled, and held down by spring Zupon the head B of lever B, as shown in tig. 2. O represents a pin which is inserted in to a hole made in the upper surface of the cam-head B', and adjusted so as to project more or less from said head, as maybe desired, by means of a set-screw, D, to which a jam-nut D is applied. When lever B is depressed the projecting end of pin C, which endis slightly rounded, as shown in iig. 2, will raise the rod L and its pin i until the upper fiat end of this pin touches the cutting edge of the tubular punchf, after which the pin i and its stein will be released from upward pressure by its lower end passing into the slot 1 ci' the cam-head B. This will allow the lower clinching head g to be moved up to the upper clinching head f, as shownin iig. 3, by a further descent ot' the leverB. It will be seen, by reference te figs. 1, 2, and 3, that the cannhead B' elevates the tube z' with its cliuching head g, and the adjustable pin C clevates the stem h and its pin hf The pin i will thus act iirconjrii-= tion with the tubular cutter-f so as to allow this cutter to make the holes through the substance into which it is desired to insert the eyelets, and also allow the lower elinching head g te insert the eyelet through the hole made in the substance, and at the same time deliver the eyelet upon the tubular cutter, after which the eyelet is clinched by and between the two headsf and g, as shown in figs. 3 and 5. Thus it will be seen that at every descent of lever-arm B a hole is made through the leather or cloth, the eyelet inserted, and then flrinly clinched.

I am aware that tapering punches'have been used for introducing eyelets through cloth, in conjunction with clinching heads, but such punches are objectionable, particularly for inserting eyelets in leather, as they do not cutout the leather and thusleave a hole for receiving the eyelet. I do not therefore lay claim to solid punches of 4a tapering form.

Directly behind the perforating and clinching devices an adjustablcgauge, E, is applied, which `.consists ot' a slotted plate with its front end turned up, which plate is secured by a. set-screw to a shelf that is secured firmly to the front edge et" frame A, as shown in fig. 3. This gauge E is used for allowing the eyelets to be inserted at a uniform `distance from the edge et' a. picceot' cloth, and in a line'parallel thereto. I On one side of the ea'ilargod head?) a right-.angular plate, I?, is secured, the horizontal portion of which is slotted, as shown in tig. 2, for receiving through it a screw-stud, s, which is formed on an adjustable plate, G. This stud s receives upon it a thumb-screw or nut, t, by which'plat-e G can be firmly clamped to plate F, as shown in ligs. 1 and 2. A stud, v, projects perpcndicularly from plate G and serves to receive an eyelet which has been inserted into a'. piece oi cloth, se as to determine the distance from such eyclctfor the insertion of another. By means of'this gauge-pin the cloth is not only held in place, but it is held in the desired position for the insertion of other eyelets, thereby having the eyelets at regular distances apart. By loosening the thumb-screw t. the pin or stud i.' can beset at, any required distance from the Ihollow' punch f.

The operation of' inserting eyelets is as follows:

The gauges E and o are properly adjusted and secured. An eyelet is slipped over the projecting endof pin h, with its smallest end uppermost, as -shown in fig. The cloth which is to reccivethis eyelet is adjusted beneath `the punchf, and the lever B depressed, either,by hand, or by a trcadle. The first movement of lever B brings pin 7L up closely against the punch f and cuts the hole. The second movement of this lever raises the clinching head g and inserts the eyelet through the hole made in the cloth, and at the same time delivers the eyelet upon the punch f, which latter receives the head g. The finalv move-ment of said lever brings the heady suiiciently close to the head f to clinch the eyelet. When lever B is released the parts will fall back to tlre positions shown in tig. 2.. This operation is repeated for every eyelet which is inserted into the fabric, thelast eyelet being the one placed over the pin t', thus having them at regular distan-ces apart.

What I claim asnew, and desire to secure by Letters -Patent, is-

li. An eyel-et-clinehing head, having a tubular punch', or cutter, f, applied to it, incombination with a perforated clinching head, having a pin, 7i, through it, said parts being arranged andleperated so as to cut a hole through cloth or other substances, insert and clinch an eyelet at one operation, substantially as described.

2. The clinching head f', provided with a tubular cutting punch,f, substantially as and for the purposes set forth. I

3. In combination with eyelet-punching and elinehing devices, constructed substantially as described, I claim the movable tube t', and movable stem L t, with their springs 7c Z and cam-lever B, arranged so that they shall operate substantially as described.

4. The adjustable pin C, applied to the `cam-head B of level` B, for moving the stem 7i t, substantially as described. j

5. In combination with the machine, constructed as herein described, I claim the adjustable gauge pitre, substantially as set forth.

6. In combination with the machine, constructed as herein described, I claim the adjustable vgauge E and l adjustable gauge-pin u, substantially as described.
